So, what is PUR glue? Well, it's a hot melt glue, yes, but what makes it different?
What is PUR Glue?
PUR glue is a specific type of hot melt glue.
PUR glue (polyurethane reactive glue) is a more recent development in the hot melt world. They polymerize when applied, forming a much stronger bond than other hot melts. It is quite flexible and can be used in a wider range of temperatures than most hot melts.
PUR glue is often used in perfect binding as book binding adhesive. Our animal glue is also used in other methods for book binding adhesive.
Advantages of Using PUR Glue
The bonds occur when the chemicals in the glue draw moisture out of the air. PUR glues are incredibly strong and flexible, and work beautifully as book binding adhesive using the perfect binding method on difficult jobs.
Like most hot melts, they tackify immediately, although PUR glues do require a 24-hour curing period. Common uses for PUR glue include bookbinding spine glue in certain binding applications. Other bookbinding methods depend on animal glue manufacturers like L.D. Davis for hide glue to get the job done correctly.
Main Uses of PUR Glue
PUR glue is often used in the following industries:
- Packaging
- Woodworking
- Electronics
- Shoes
- Printed film
LD Davis has been manufacturing eco-adhesives for over nine decades. In more recent years we have expanded our products line to distribute hot melts, PUR glue, stay tape and other types of adhesives to fit your needs.
Whatever the application, we will come up with an adhesive solution.
